Hello,I operate a street rod shop that one of my specialties is wiring.When I need a wiring diagram I go to the Library. Usually the larger the libraries have more older automotive referance books. Also you may try type in the words"Automotive Research Library"on the internet. This will take you to a site that has all the referance books that were used by Bill Harrah. The site says your can request a form for inforamtion, and wiring diagrams are listed in the information list. I don't know yet if there are any charges, but it looks promising.Maybe this will help--Paul
